Privacy Policy

Effective Date: November 5, 2026

This Privacy Policy applies to the mobile application Calmia (Package ID: com.sleep.sound.white.noise.z), which is developed, owned, and operated by TapVolt Limited ("we", "us", or "our").

1. Overview

We respect your privacy and are committed to protecting it through our compliance with this policy. This Privacy Policy describes how TapVolt Limited collects, uses, maintains, and discloses information collected from users of Calmia.

2. Information We Collect

Calmia is designed to provide ambient, flight, and continuous background focus soundscapes without compromising your personal data privacy.

a. Information You Provide

We do not require users to create an account or provide personally identifiable information (such as your full name, home address, or telephone number) to access core app functionality.

b. Non-Personal & Automatically Collected Information

To ensure system stability, improve service performance, and deliver personalized experiences (including advertising), we and our third-party integrated service providers (such as Google Play Services and AppLovin) may collect certain technical non-personal data, including:

• Device Identifiers (such as Advertising ID / IDFA).
• Device technical specifications (device model, OS version, system language settings).
• App usage diagnostics, error logs, and performance metrics.

3. Background Audio & Audio Permissions

The application enables persistent audio playback to deliver continuous ambient audio while operating in the background or when your screen is locked. This operation functions strictly on-device and does not record, record-store, or transmit audio signals from your microphone or physical environment.

4. How We Use Information

We use collected data solely for the following business purposes:

• To maintain, optimize, and deliver ambient soundscape playback features.
• To diagnose operational performance and resolve application crashes.
• To serve relevant ad placements and measure advertising efficiency via integrated third-party ad networks (e.g., AppLovin).
• To satisfy developer guidelines, statutory requirements, and legal compliance standards.

5. Third-Party Services & Data Sharing

We do not trade, sell, or rent users' personal identification information to others. Anonymous diagnostic or ad-performance data may be shared with trusted third-party partners strictly for technical maintenance, analytics, and monetization in alignment with their respective privacy standards.

6. Children's Privacy

Our application is not intended for or directed to children under 13 years of age (or under 16 in relevant jurisdictions). We do not knowingly collect personal data from children. If we become aware that a child has provided us with personal information without parental consent, we will take immediate steps to delete such data.
